The best demonstration that applies to Newton's Third Law of motion would be D) When you walk your foot pushes down on the ground while the ground pushes back on your foot.
------------------
Newton's Third Law states that for every action, there is an equal and opposite reaction. This is actually explains that forces come in pairs and forces are an interaction between two objects. As per the correct option given in the question explains Newton’s Third Law.
------------------
When you walk your foot (say object A) pushes down on the ground while the ground (say object Q) pushes back on your foot with the same force but in the opposite direction.
The capacity of muscles to maintain a force, over a period of time or uses a single maximum force over any range of motion is called Muscular Endurance. It can sustain repetitive contractions against a resistance for an extended period of time. It is one of the constituents of muscular fitness.
I believe the answer is C, and not D because B is incorrect. The water and wind erosion smoothen the rock creating a mushroom shape.
Answer:
Explanation:
Given:
Thickness of the paperweight cube,
apparent depth from one side of the inbuilt paper in the plastic cube,
apparent depth from the other side of the inbuilt paper in the plastic cube,
Now as we know that refractive index is given as:
- Let the real depth form first side of the slab be,
- Then the depth from the second side of the slab will be,
Since refractive index for an amorphous solid is an isotropic quantity so it remains same in all the direction for this plastic.
Now the refractive index:
Data given:
V=45m/s
t=11s
Δx=?
Formula needed:
V=Δx/t
Solution:
Δx=v×t
Δx=45m/s×11s
Δx=495m
According to my solution B) is the most accurate
